== NAME

FvwmIconMan - an fvwm icon manager

== SYNOPSIS

FvwmIconMan is spawned by fvwm, so no command line invocation will work.

== DESCRIPTION

FvwmIconMan is an icon manager modeled after the TWM icon manager. The
user may have multiple icon managers, each of which armed with a list of
window types which it manages. For example, the user may have one
manager which lists only emacs windows, and another which lists
everything else. You may also specify what resolution each icon manager
uses, for example, one icon manager may manage windows on all desks, and
another may manage only those on the current desk, page or screen.
FvwmIconMan can display the miniature icons provided by fvwm for its
managed windows. The managers may have a maximum number of columns (and
so grows vertically), a maximum number of rows (and then grows
horizontally), or stay at a fixed size, and adjust the size of the
window buttons to fit (think win95's Taskbar). And when support is
compiled in for the X Shape extension, then the manager windows may be
shaped.

You can specify actions to be run when mouse, or key events are
received. For example, you could bind the first mouse button to iconify
the selected window, and make bindings for the arrow keys to navigate
the manager window without the mouse.

FvwmIconMan can be set to display which window currently has the
keyboard focus, and by binding the select event (see below) to the fvwm
Focus function, you can emulate the TWM icon manager's behavior.

== INITIALIZATION

During initialization, FvwmIconMan searches though the fvwm
configuration file for the options which are described below. It is
highly recommended that you make FvwmIconMan be a sticky window. And if
you want to make use of the followfocus option, and/or binding an action
to Focus, then you should make FvwmIconMan clicktofocus. Also, when
using the Shape option, it's recommended that the FvwmIconMan window not
be decorated at all by fvwm.

== INVOCATION

FvwmIconMan can be invoked by inserting the line 'Module FvwmIconMan' in
the .fvwm2rc file. If FvwmIconMan is to be spawned during fvwm's
initialization, then this line should be placed in the StartFunction
declarations, or it can be bound to a menu, mouse button, or keystroke
to invoke it later.

If you wish to run FvwmIconMan in a transient mode, such as with the
built in window list, then pass "-Transient" as an argument. The
invocation "Module FvwmIconMan -Transient" will do nicely. In this mode,
FvwmIconMan will pop up one manager window directly under the cursor.
When the mouse button is released, it will execute the appropriate
action, and then exit. Things are somewhat complicated by the fact that
you can specify that FvwmIconMan creates multiple manager windows,
behavior which is unsuitable when running transiently. So, when running
transiently, FvwmIconMan will only create one manager window. Use the
manager id 'transient' to specify options for this manager window.

FvwmIconMan may accept an alias name as an argument. For example,
"Module FvwmIconMan FvwmIconMan-Variant2".

== CONFIGURATION OPTIONS REFERENCE CHART

FvwmIconMan has acquired quite a few options. I assume others share my
dislike of paging though a long man page, so here is a terse reference
chart describing the available options. They are described in more
detail in the next section.

== CONFIGURATION OPTIONS

With the exception of the nummanagers option, all of the options may be
defined on a per-manager basis. So, for example, the user may have his
emacs manager with a red foreground, and his xterm manager with a blue
one. A configuration line may therefore have one of two forms:

*FvwmIconMan: OptionName OptionValue::
  To specify that the _OptionName_ takes the value _OptionValue_ for all
  managers.
*FvwmIconMan: ManagerId OptionName OptionValue::
  To specify that the option _OptionName_ takes the value _OptionValue_
  for manager _ManagerId_. _ManagerId_ may either be a positive integer,
  or the string "transient". An integer id refers to managers which
  FvwmIconMan creates when running normally, and an id of "transient"
  refers to the single manager which FvwmIconMan creates when running
  transiently.

The old syntax, that uses an asterisk instead of white spaces before
_ManagerId_ and _OptionName_, is supported too, but it is obsolete now.

The following options may be specified:

*FvwmIconMan: NumManagers num::
  _num_ is a positive integer specifying the total number of icon
  managers. Since FvwmIconMan would like to know how many managers there
  are before handling any manager specific options, this should come
  first. The default is 1.
*FvwmIconMan: [id] Action type binding::
  Binds an FvwmIconMan command to an event. _Type_ may be one of the
  values: Key, Mouse, or Select. Actions are described in the following
  section ACTIONS.
*FvwmIconMan: [id] Background background::
  Specifies the default background color.
*FvwmIconMan: [id] ButtonGeometry geometry::
  Specifies the initial geometry of an individual button in pixels. If
  the specified height is 0, then the button height is determined from
  the font size. X and Y coordinates are ignored.
*FvwmIconMan: [id] Colorset colorset::
  The default colorset used. Overrides background and foreground.
*FvwmIconMan: [id] DrawIcons value::
  If your version of fvwm is capable of using mini icons, then this
  option determines if FvwmIconMan displays the mini icons. Otherwise,
  it generates an error message. "true" means that mini icons are shown
  for iconified windows, "false" that mini icons are never shown, and
  "always" that mini icons are shown for all windows.
*FvwmIconMan: [id] FocusAndSelectButton style [forecolor backcolor]::
  Same as the plainbutton option, but specifies the look of buttons
  which are both selected, and have the keyboard focus.
*FvwmIconMan: [id] FocusAndSelectColorset colorset::
  Works like focusandselectbutton but uses colorsets instead. The style
  setting can still only be applied with focusandselectbutton.
*FvwmIconMan: [id] FocusButton style [forecolor backcolor]::
  Same as the plainbutton option, but specifies the look of buttons
  whose windows have the keyboard focus.
*FvwmIconMan: [id] FocusColorset colorset::
  Works like focusbutton but uses colorsets instead. The style setting
  can still only be applied with focusbutton.
*FvwmIconMan: [id] FollowFocus boolean::
  If _true_, then the button appearance reflects which window currently
  has focus. Default is false.
*FvwmIconMan: [id] Font font::
  Specifies the font to be used for labeling the buttons. The default is
  8x13.
*FvwmIconMan: [id] Foreground foreground::
  Specifies the default foreground color.
*FvwmIconMan: [id] Format formatstring::
  A printf like format string which describes the string to be printed
  in the manager window for each managed window. Possible flags are: %t,
  %i, %c, %r, and %s for the window's title, icon title, class, resource
  name, or screen respectively. The default is "%c: %i".
*FvwmIconMan: [id] IconName iconstring::
  Specifies the window icon name for that manager window. _Iconstring_
  may either be a single word, or a string enclosed in quotes. The
  default is "FvwmIconMan".
*FvwmIconMan: [id] IconAndSelectButton style [forecolor backcolor]::
  Same as the plainbutton option, but specifies the look of buttons
  whose windows are iconified and the button is selected.
*FvwmIconMan: [id] IconButton style [forecolor backcolor]::
  Same as the plainbutton option, but specifies the look of buttons
  whose windows are iconified.
*FvwmIconMan: [id] IconAndSelectColorset colorset::
  Works like IconAndSelectButton but uses colorsets instead. The style
  setting can still only be applied with iconbutton.
*FvwmIconMan: [id] IconColorset colorset::
  Works like iconbutton but uses colorsets instead. The style setting
  can still only be applied with iconbutton.
*FvwmIconMan: [id] ManagerGeometry geometry::
  Specifies the initial geometry of the manager, in units of buttons. If
  _height_ is 0, then the manager will use _width_ columns, and will
  grow vertically once it has more than _width_ windows. Likewise, if
  _width_ is 0, it will use _height_ rows, and grow horizontally. If
  both are nonzero, then the manager window will be exactly that size,
  and stay that way. As columns are created, the buttons will narrow to
  accommodate. If the geometry is specified with a negative y
  coordinate, then the window manager will grow upwards. Otherwise, it
  will grow downwards.
*FvwmIconMan: [id] MaxButtonWidth width::
  Defines a maximum for the width of a button (in pixels). By default
  there is no maximum. A value of 0 resets the default. The maximum is
  only used with a non growing manager (the ManagerGeometry option
  specifies non zero width and height).
*FvwmIconMan: [id] MaxButtonWidthByColumns col::
  This is another way to set the button width. col is the number of
  columns of icons. The button width is determined by dividing the total
  width of FvwmIconMan by the number of columns. For example if the
  width of FvwmIconMan manager is 1024, MaxButtonWidthByColumns is 4
  then MaxButtonWidth is 256. This is useful when you do not know, at
  config time, the width of the manager, for example, for a swallowed
  FvwmIconMan.
*FvwmIconMan: [id] NoIconAction action::
  Tells FvwmIconMan to do _action_ when a NoIcon style window is
  iconified or de-iconified. Relevant coordinates are appended to
  _action_ so that the icon can be traced to an FvwmIconMan button. An
  example action is "*FvwwmIconMan: NoIconAction SendToModule
  FvwmAnimate animate". A blank or null action turns this feature off.
*FvwmIconMan: [id] PlainButton style [forecolor backcolor]::
  Specifies how normal buttons look. _style_ may be one of _flat_, _up_,
  _down_, _raisededge_, or _sunkedge_, and describes how the button is
  drawn. The color options are both optional, and if not set, then the
  default colors are used. If on a monochrome screen, then the _style_
  option is ignored, but must still be set.
*FvwmIconMan: [id] PlainColorset colorset::
  Works like plainbutton but uses colorsets instead. The style setting
  can still only be applied with plainbutton.
*FvwmIconMan: [id] ReliefThickness num::
  _num_ is an integer specifying the number of pixels thick that the
  relief at the edge of non-flat buttons should be. Setting this to 0
  will produce flat buttons, as if the values for
  _FocusAndSelectButton_, _FocusButton_, _IconAndSelectButton_,
  _IconButton_, _PlainButton_, _SelectButton_, and _TitleButton_ were
  all set to _flat_. If _num_ is negative, the button will be inverted
  as if you had used _Reverse_ for all classes.
*FvwmIconMan: [id] Resolution [_filter(s)_]::
  Specifies a list of _filters_, separated by spaces, that configure which
  windows are displayed. If no filters are given, then all windows of the
  appropriate type are shown (see the show and dontshow options below).
  Each _filter_ then limits the windows that are displayed and may take
  one of the following values: desk, page, screen, !desk, !page, !screen,
  or invert. _desk_ only shows windows on the current desk, and _page_
  only shows windows on the current page. _!desk_ and _!page_ only show
  windows not on the current desk or page respectively. _invert_ reverses
  the filter displaying the windows that did not match.
+
Notes: _page_ and _desk_ are independent. If the only filter is _page_,
then you will see windows on the current page on all desks. To only see
windows on the current page and desk (the default) you need both filters,
'desk page'. You can only have one of desk/!desk, page/!page, or
screen/!screen, the last one issued take precedence. The invert filter
reverses the whole filter so 'invert desk page' is not the same as
'!desk !page'. Sticky windows are visible on all pages and desks, so
they match all page and desk filters, but won't match the inverted filter.
+
The filters can take additional parameters to state which desk, page,
or screen to show (or not show). _[!]desk [n]_ can take the desk number,
which will only show windows (not) on the stated desk. _[!]page [x] [y]_
can take the horizontal, _x_, and vertical, _y_, page numbers, which will
only show windows (not) on the stated page.
+
_[!]screen [S]_ shows windows (not) on monitor _S_, which can be:
+
--
* _NAME_: The "NAME" of the specific RandR monitor.
* _c_: The current RandR monitor (containing the pointer)
* _p_: The primary RandR monitor
* _g_: The global monitor
--
+
Since all windows are on the global monitor, _screen g_ effectively does
nothing. _c_ is the current monitor at the time resolution is issued, and
once set will not change. This filter is best used with a RandR _NAME_.
+
This configuration line is respected when FvwmIconMan is running as
well, the resolution is changed dynamically when sent to fvwm.

*FvwmIconMan: [id] Reverse class::
  Causes certain classes of buttons to have their relief lines reversed
  so that up and down styles are reversed. This has no affect on flat
  buttons. The class can be icon, normal or none. The default is none.
*FvwmIconMan: [id] SelectButton style [forecolor backcolor]::
  Same as the plainbutton option, but specifies the look of buttons when
  the mouse is over them.
*FvwmIconMan: [id] SelectColorset colorset::
  Works like selectbutton but uses colorsets instead. The style setting
  can still only be applied with selectbutton.
*FvwmIconMan: [id] Shape boolean::
  If _True_, then use make the window shaped. Probably only useful if
  you have multiple columns or rows. If FvwmIconMan wasn't compiled to
  support the Shape extension, this generates an error message. When
  using shaped windows, it's recommended that a fvwm style is made for
  FvwmIconMan that has no borders. Otherwise, fvwm will get confused.
*FvwmIconMan: [id] Sort value::
  If _name_, then the manager list is sorted by name. If _namewithcase_,
  then it is sorted by name sensitive to case. If _id_, then the manager
  list is sorted by the window id, which never changes after the window
  is created. If _weighted_, then the manager list is sorted by weight
  (see the description of _sortweight_ below). Or it can be set to
  _none_, which results in no sorting. Default is _name_.
*FvwmIconMan: [id] SortWeight weight pattern-list::
  Assigns the specified _weight_ to windows that match _pattern-list_.
  The list is made up of patterns of the form _type=pattern_, where type
  is one of _class_, _resource_, _title_, _icon_, or, _screen_ and pattern is an
  expression of the same format used in the fvwm style command
  (minimalistic shell pattern matching). Multiple sort weights can be
  given. Each window is matched against the list of sort weights, in
  order, and is given the weight from the first match. Lower-weighted
  windows are placed first in the manager list. For example:
+
....
  *FvwmIconMan: Sort weighted
  *FvwmIconMan: SortWeight 1 class=XTerm title=special*
  *FvwmIconMan: SortWeight 10 class=XTerm
  *FvwmIconMan: SortWeight 5
....
+
In this example, xterm windows whose titles start with "special" (weight
1) are listed first, followed by everything but other xterms (weight 5),
and the other xterms (weight 10) are listed last. If no default weight
(empty pattern list) is given, the default weight is 0. Only relevant if
the sort type is set to _weighted_.

*FvwmIconMan: [id] Title title-string::
  Specifies the window title string for that manager window.
  _Titlestring_ may either be a single word, or a string enclosed in
  quotes. The default is "FvwmIconMan". This will be drawn in the title
  bar of the manager window, if any, and in the title button, which is
  the button drawn when the manager is empty.
*FvwmIconMan: [id] TitleButton style [forecolor backcolor]::
  Same as the plainbutton option, but specifies the look of the title
  button (the button drawn when the manager is empty). The manager's
  title is drawn in the title button.
*FvwmIconMan: [id] UseWinList boolean::
  If _true_, then honor the WinListSkip style flag. Otherwise, all
  windows are subject to possible management according to the show and
  dontshow lists.
+
The two following options control which windows get handled by which
managers. A manager can get two lists, one of windows to show, and one
of windows to ignore. If only the _show_ list is given, then that
manager will show only the windows in the list. If only the _DontShow_
list is given, then the manager will show all windows except those in
the list. If both lists are given, then a window will be shown if it is
not in the _DontShow_ list, and in the _Show_ list. And finally, if
neither list is given, then the manager will handle all windows. Each
list is made up of patterns of the form _type=pattern_, where type is
one of _class_, _resource_, _title_, or _icon_, and pattern is an
expression of the same format used in the fvwm style command
(minimalistic shell pattern matching). Quotes around the pattern will be
taken as part of the expression. If a window could be handled by more
than one manager, then the manager with the lowest id gets it.

*FvwmIconMan: [id] Show pattern list::
  If a window matches one of the patterns in the list, then it may be
  handled by this manager.
*FvwmIconMan: [id] DontShow pattern list::
  If a window matches one of the patterns in the list, then it may not
  be handled by this manager.
*FvwmIconMan: [id] ShowTransient boolean::
  Show transient windows in the list (default false).
*FvwmIconMan: [id] ShowOnlyIcons boolean::
  Only iconified windows are shown if _boolean_ is true.
*FvwmIconMan: [id] ShowNoIcons boolean::
  Only windows that are not iconified are shown if _boolean_ is true.
*FvwmIconMan: [id] ShowOnlyFocused boolean::
  Only window with the focus is shown if _boolean_ is true.
+
The following two options control tips.

*FvwmIconMan: [id] Tips value::
  where _value_ can be always, needed or false. Default is false, no
  tips are displayed. With always, tips are enabled. With needed, a tip
  is displayed only if either the button string is truncated or the tip
  string is not equal to the button string. This configuration line is
  respected when FvwmIconMan is running as well.
*FvwmIconMan: [id] TipsDelays delay [mappeddelay]::
  where _delay_ and _mappeddelay_ are time out values in milliseconds.
  If no _mappeddelay_ is given _delay_ is assumed. Default is 1000 300.
  When the cursor is on a button, FvwmIconMan wait _delay_ milliseconds
  before displaying the tip. In the case where a tip is already mapped
  and the cursor goes to another button, FvwmIconMan waits _mappeddelay_
  milliseconds before displaying the new tip.
*FvwmIconMan: [id] TipsFont fontname::
  Specifies the font to be used for tips. Default is the default fvwm
  font.
*FvwmIconMan: [id] TipsColorset colorset::
  Specifies the colors for tips window. Default is colorset 0.
*FvwmIconMan: [id] TipsFormat formatstring::
  Similar to the Format option but for the tips window. The default is
  the format string from the Format option.
*FvwmIconMan: [id] TipsBorderWidth pixels::
  Specifies the border width (in pixels) of the tips window. Default is
  1.
*FvwmIconMan: [id] TipsPlacement value::
  where _value_ can be up, down, right, left, updown or leftright. This
  value specifies the position of the tips window relative to its
  button. Default is updown where buttons on the top half of the screen
  get tips below the button, otherwise the tips are above the button.
*FvwmIconMan: [id] TipsJustification value::
  where _value_ can be leftup, rightdown or center. Specifies the
  justification (direction) of the tips window relative to its button
  after the tips window has been placed. Default is leftup which means
  that if a tip is placed above or below its button, then the left
  border of the tip and of the button are aligned. If the tip is placed
  on the left or on the right of its button, leftup aligns the top
  borders. rightdown and center work like leftup but in different
  directions. The alignment is adjusted by the TipsOffset option. See
  next option.
*FvwmIconMan: [id] TipsOffsets placementoffset justoffset::
  where _placementoffset_ and _justoffset_ are offsets in pixels for the
  TipsPlacement and TipsJustification configuration option. Default is 3
  2.

== ACTIONS

Actions are commands which may be bound to an event of the type: a key
press, a mouse click, or the mouse entering a window manager button -
denoted by the action types _Key_, _Mouse_, and _Select_.

Normally, actions bound to a mouse click are executed when the button is
pressed. In transient mode, the action is executed when the button is
released, since it is assumed that FvwmIconMan was bound to some mouse
event. A tip/warning: FvwmIconMan still keeps track of the mouse button
and any modifier keys in this case, so if you bind FvwmIconMan to say,
meta-button3, then it would be wise to ensure that the action you want
to execute will be executed when the meta-button3 event occurs (which
would be the button release, assuming you kept your finger on the meta
key).

The syntax for actions are:

Key actions: Key Keysym Modifiers FunctionList::
  _Keysym_ and _Modifiers_ are exactly the same as for the fvwm _Key_
  command.
Mouse actions: Mouse Button Modifiers FunctionList::
  _Button_ and _Modifiers_ are exactly the same as for the fvwm _Mouse_
  command.
Select actions: Select FunctionList::

A _FunctionList_ is a sequence of commands separated by commas. They are
executed in left to right order, in one shared context - which currently
only contains a pointer to the "current" button. If a button is selected
(typically by the mouse pointer sitting on it) when the action is
executed, then the current button is initialized to that button.
Otherwise, it points to nothing.

Most of the available commands then modify this "current" button, either
by moving it around, making it become the selected button, or sending
commands to fvwm acting on the window represented by that button. Note
that while this current button is initialized to be the selected button,
the selected button does not implicitly follow it around. This way, the
user can send commands to various windows, without changing which button
is selected.

Commands take five types of arguments: _Integer_, _Manager_, _Window_,
_Button_, and _String_. A _String_ is a string specified exactly as for
fvwm - either in quotes or as a single word not in quotes. Again, you
may bind a sequence of commands to an event, by listing them separated
by commas.

_Window_ and _Button_ types look exactly the same in the .fvwm2rc file,
but are interpreted as either specifying a managed window, or a
FvwmIconMan button representing a window. They can either be an integer
(which is interpreted module N where N is the number of buttons - so 0
is the first and -1 is the last), or one of the strings: _Select_,
_Focus_, _Up_, _Down_, _Right_, _Left_, _Next_, _Prev_. _Select_ and
_Focus_ refer to the currently selected or focused button or window.
_Up_, _Down_, _Right_, and _Left_ refer to the button or window above,
below, to the right of, or to the left of the current button in the
manager window, allowing navigation around the manager window. _Next_
and _Prev_ designates the window, button, or manager after or before the
current button, allowing navigation of the one dimensional list of
windows which is drawn in the manager window. If the manager is sorted,
_Next_ and _Prev_ move through the windows in the sorted order.

The _Manager_ type can either be an integer, _Next_, or _Prev_. The
meaning is analogous to that of the _Button_ type, but in terms of the
integral index of the managers, restricted to managers which are
nonempty.

The following functions are currently defined:

bif Button Integer/String::
  A relative branch instruction. If _Button_ is _Select_ or _Focus_,
  then take the branch if there is a selected button or a focused
  button. If _Button_ is an integer, then branch if nonzero. If it is
  one of _Up_, _Down_, _Right_, _Left_, _Next_, _Prev_, then the branch
  is taken when the current button can move in that direction. If the
  branch is taken, then _Integer_ commands are skipped. No backwards
  branches are allowed.
bifn Button Integer/String::
  The complement of bif. The branch is taken if _Button_ evaluates to
  false, by the criteria listed for bif.
gotobutton Button::
  Sets current button to _Button_. If _Button_ is an integer, then the
  current button is set to _Button_ modulo the number of buttons, in the
  whichever manager contains the selected button, if any.
gotomanager Manager::
  Sets button to button 0 of _Manager_. This will only go to a visible,
  nonempty manager. So an integral argument is taken modulo the number
  of such managers.
jmp Integer/String::
  Executes a relative jump of _Integer_ instructions. Backwards jumps
  are not allowed. The jump is computed relative to the instruction
  following the jmp.
label String::
  Provides a label that previous instructions can jump to. It will not
  be visible to subsequent jump instructions, and the same label can be
  used multiple times in the same instruction list (though it would be
  perverse to do so.)
print String::
  Prints _String_ to the console. Useful for debugging actions.
printdebug::
  Prints defined actions to the console. Should only be used by
  developers. To enable this command, set CONFIG and FUNCTIONS variables
  to '1' in the modules/FvwmIconMan/debug.h and recompile this module.
quit::
  Quits FvwmIconMan.
refresh::
  Causes all manager windows to redraw themselves.
ret::
  Stop executing the entire action.
searchback String::
  Sets button to button before the current one whose printed string in
  the manager window matches specified _String_, which may contain
  wildcards.
searchforward String::
  Sets button to button after the current one whose printed string in
  the manager window matches specified _String_, which may contain
  wildcards.
select::
  Selects the current button, if any. If a select action has been
  specified, it will then be run. Therefore, it is considered unwise to
  set the select button in the select action.
sendcommand Command::
  Sends the fvwm command _Command_ to the window represented by the
  current button, if any.
warp::
  Warps cursor to current button, if any.

*Examples:*

....
gotobutton select, gotobutton Down, select
....

Selects the button below the currently selected button. Since the
current button is already initialized to the selected button, this may
be shortened to "gotobutton Down, select".

....
gotobutton Up, select
....

Selects the button above the currently selected button.

....
gotobutton 0, select
....

Selects the first button of the current manager. If there is no current
manager, which is the case when no button is selected, then this does
nothing.

....
gotobutton -1, select
....

Selects the last button of the current manager.

....
gotobutton focus, select
....

Selects the button corresponding to the focused window.

....
gotobutton focus, Iconify
....

Sends the fvwm command Iconify to the focused window. Note that this
does not change the selected button.

....
bif Next 3, gotobutton 0, select, ret, gotobutton Next, select
....

If a button is selected, and it's the last button, go to button 0. If
it's not the last button, go to the next button. Otherwise, do nothing.
Basically, this action cycles through all buttons in the current
manager.

....
bif select 7, bif focus 3, gotomanager 0, select, ret, gotobutton focus, \
select, ret, gotobutton down, select
....

This is good for sending to FvwmIconMan with a SendToModule command. If
there is a selected button, it moves down. Otherwise, if there is a
focused button, it is selected. Otherwise, button 0 of manager 0 gets
selected.

....
bif select Select, bif focus Focus, gotomanager 0, select, ret, label Focus, \
gotobutton focus, select, ret, label Select, gotobutton down, select
....

Same as previous, but using the label instruction.

In addition to being bound to keys and mice, actions can be sent from
fvwm to FvwmIconMan via the SendToModule command. Don't quote the
command when using SendToModule. Also, due to a bug in the current
version of fvwm, don't quote FvwmIconMan either.

== SAMPLE CONFIGURATIONS

This first example is of a the simplest invocation of FvwmIconMan, which
only has one manager, and handles all windows:

....

# fvwm initialization

Style "Fvwm*"      Icon toolbox.xpm,NoTitle,NoHandles,Sticky

This example is the Reader's Digest version of my personal
configuration. It has two managers, one for emacs and one for everything
else, minus things with no icon title. Only windows on the current page
are displayed. The use of the _drawicons_ and _shape_ options requires
that fvwm and FvwmIconMan are compiled with the correct options. Note
how the geometry and show options are specified per manager, and the
others are common to all:

....

== UNFINISHED BUSINESS

There is one bug that I know of. A honest to goodness solution to this
would be appreciated. When an icon manager is set to grow upwards or
leftwards, on some machines it may wander occasionally.

It doesn't handle windows without resource names as gracefully as it
should.
